What is Alooma

Alooma (acquired by Google Cloud in 2019) was a streaming ETL platform that enabled real-time ingestion of data from various sources into BigQuery. It provided a visual pipeline editor to map, transform, and route data with minimal code, automatically handling schema changes and ensuring exactly-once delivery. While Alooma as a standalone product is retired, many of its features have been integrated into Google Cloud’s Dataflow and Pub/Sub pipelines.

Pros

  • Real-time streaming ETL with automatic schema drift handling.
  • Minimal coding: visual pipeline UI with built-in connectors to databases, Kafka, APIs, and SaaS apps.
  • Exactly-once delivery guarantees to BigQuery, eliminating duplicate data.

Cons

  • Standalone Alooma product is discontinued—functionality now lives in GCP services (e.g., Dataflow, Data Fusion).
  • Migrating legacy Alooma pipelines to GCP-native services requires rework, as UI and features differ from original Alooma.

Google Cloud’s Dataflow (Alooma integration):

What I like about Alooma

Alooma’s ease of connecting live streaming data sources directly into BigQuery with automated schema management was revolutionary for our real-time analytics.

What I dislike about Alooma

Since Google integrated Alooma into its native services, the standalone product no longer exists, so new users must migrate to Dataflow or Data Fusion.

What I like about Weld

First and foremost, Weld is incredibly user-friendly. The graphical interface is intuitive, which makes it easy to build data workflows quickly and efficiently. Even with little experience in SQL and pipeline management, we found that Weld was straightforward and easy to use. What really impressed me, however, was Weld's flexibility. It was able to handle data from a wide variety of sources, including SQL databases, Google Sheets, and even APIs. The solution also allowed us to customize my data transformations in a way that best suited my needs. Whether I needed to clean data, join tables, or aggregate data, Weld had the necessary tools to accomplish the task. Weld's performance was also exceptional. I was able to run large-scale ETL jobs quickly and efficiently, with minimal downtime via a Snowflake instance and visualization via own-hosted Metabase. The solution's scalability meant that I could process more data without any issues. Another standout feature of Weld was its support. I never felt lost or unsure about how to use a particular feature, as the support team was always quick to respond to any questions or concerns that I had. Overall, I highly recommend Weld as an ETL solution. Its user-friendliness, flexibility, performance, and support make it an excellent choice for anyone looking to streamline their data integration processes. I will definitely be using Weld for all my ETL needs going forward.

What I dislike about Weld

Weld is still limited to a certain number of integrations - although the team is super interested to hear if you need custom integrations.

Alooma vs Improvado: Ease of Use and User Interface

Alooma

Alooma’s web-based pipeline builder allowed users to drag-and-drop connectors for streaming or batch data, apply transformations, and route data to BigQuery with just a few clicks. The interface auto-generated SQL when possible.

Improvado

Improvado is known for its ease of use and strong support, making it a good choice for businesses looking to integrate multiple media platforms with minimal effort.

Alooma vs Improvado: Pricing Transparency and Affordability

Alooma

No longer available as a separate product. Users adopt equivalent GCP services (Dataflow, Data Fusion) which have pay-as-you-go pricing under the GCP pricing model.

Improvado

Improvado's pricing is custom, which can be expensive depending on data volumes, making it less accessible for small businesses but valuable for larger enterprises with extensive data needs.

Alooma vs Improvado: Comprehensive Feature Set

Alooma

Alooma supported real-time ingestion from Kafka, databases (MySQL, PostgreSQL), logs, REST APIs, and SaaS apps, with built-in transformations (masking, enrichment). It automatically handled schema changes, and could write to BigQuery partitions.

Improvado

Improvado offers automation features and flexibility in data management and reporting, catering well to agencies handling multiple accounts.

Alooma vs Improvado: Flexibility and Customization

Alooma

Users could write custom JavaScript transforms or Python UDFs for complex logic. The platform managed infrastructure, but custom connectors required Eloqua code or support.

Improvado

Improvado provides flexibility in data integration and transformation, but has limited features compared to more comprehensive platforms, which might require additional customization for some use cases.
